Do I have a 340 Rallye Challenger??

Looks like it may have had single exhaust?
I don't see a factory hanger on driver's side.
If so, it was a 318

That would be a really rare tranny! All the 833's I've seen were 4 speed manuals!

My bad I'll own it!

The driver side rear frame rail is rotted out there but if you look on the rear seat back/floor you can see the hangers on both sides. And, the plot thickens. It’s is a suregrip rear end.

Behind the hanger straps is there a bracket that looks like this on the drivers side? Should have a backing plate on the inside of the car.

Passenger side similar but welded on.
